ok i did build AKA DDL circuit and im just wondering is there way to improved for different lasers 405, 445, ...... and how, im new to this but first i build works perfect with a diode from old cd-rom drive so is there any other driver circuits we all can do at home from parts?
Sorry im Russian some times spell words wrong, but im living in US so in 3 years i have some improvements on English lol.
A bit late for me to reply to this, but why not... Yes, you can simply put a resistor across the capacitor leads. I would say 100k ohms or so would do fine for a decently fast discharge while not interrupting output current
